Granted: 2006-09-21
Abstract: A method and system for playing a lottery type game includes a gaming piece which includes a predetermined code having data indicating whether the player wins or loses the game, the data being unrecognizable to the player, such that the player does not know the outcome of the game prior to play of the game. The code is stored on the gaming piece in a memory device. The gaming piece is reusable with different codes. The code is read by a processor. The processor presents an amusement game on a display for play by the player, and the player controls game play by inputting game parameters to the processor. The processor controls the outcome of the amusement game played by the player based upon the code. A display provides an indication to the player of a game win or a game loss based upon the code.

Title: Phase-locked loop apparatus
Inventor: HORIE HIROSHI
IPC: H03L7/095
Filed: 1990-02-16
Granted: 1994-03-08
Abstract: Abstract of the Disclosure A clock signal having a predetermined frequency output from a clock generator and a signal output from a voltage controlled oscillator (VCO) and supplied through a frequency divider are supplied to a phase detector.          An output from the phase detector is supplied to a loop filter.  The loop filter supplies a voltage in accor-dance with an output from the phase detector to a first control voltage terminal of the VCO and to a phase lock-in circuit.  The phase lock-in circuit supplies a voltage in accordance with an output voltage from the loop filter to a second control voltage terminal of the VCO.  In the VCO, the sensitivity of the first control voltage terminal is lower than that of the second control voltage terminal, i.e., a rate of change in output frequency with respect to a change in second control voltage is higher than that of the first control voltage.  A phase lock detector for detecting whether or not the PLL apparatus is set in a phase-locked state is also connected to the phase lock-in circuit.  When the phase lock detector detects a phase-locked state, a trigger signal is supplied to a power Vi turn off circuit to turn off a power source Vi.          The power source Vi is connected to the clock generator, the phase detector, a part of the phase lock-in circuit, the phase lock detector, and the frequency divider.          Power is always supplied from a power source Vc to the remaining circuit of the phase lock-in circuit.

Abstract: There is disclosed a linear block copolymer comprising at least one triblock I-B-I, wherein I is a block of a polymerized conjugated diene of at least 5 carbon atoms, such as isoprene, and B is a block of a polymer of a conjugated diene, different from that of formula (1), of at least 4 carbon atoms, such as 1,3-butadiene. The B block is selectively hydrogenated, while each of the I blocks retains a sufficient amount of its original unsaturation to vulcanize the copolymer. There is also disclosed an alternative linear block copolymer containing at least one triblock of the first polymer block made from an aryl-substituted olefin, such as styrene, and the conjugated diene used to polymerize the block I, the second middle polymer block of the diene used to polymerize the block B, and the third polymer block which is the same as the first polymer block. In this alternative copolymer, the middle block is also selectively hydrogenated, thereby leaving the terminal polymer blocks with a sufficient amount of double bonds to vulcanize the copolymer. The polymers can be crosslinked or functionalized through the terminal blocks containing the vinyl unsaturation. There are also disclosed random and star-branched block and random copolymers made from the same monomers as the linear block copolymers.         Also disclosed are methods of producing and selectively hydrogenating the polymers.

Abstract: The raising structure according to the invention is intended to raise a manhole cover to the level of the resurfacing new layer of asphalt. The raising structure comprises a pair of superposed concentric rings one of which is slightly smaller than the other one so that the outer diameter of the smaller one is slightly smaller than the inner diameter of the other one. The rings are maintained in a spaced relationship by a set of spacer legs disposed around the periphery of the inner ring. Each of the legs have one end secured to the outer periphery of the small ring and the outer end of the leg is secured to the inner periphery of the larger ring. The legs are characterized by at least one bent section between both ends of the legs. The bent section extends in a plane tangent to the outer periphery of the smaller ring and the inner periphery of the larger ring. The bent section is adapted to define a weak section in the legs for allowing a change in the angle of the bent upon pressure on one of the rings.
